APPLICATIU
AUTOMATIC CHARGE COUNT INTERRUPT AND CLEAR
In applications where a CLR pulse is unavailable, it’s easy
to make the LTC4150 run autonomously, as shown in
Figures 5 and 6. If the microcontroller V
CC
is less than or
equal to the battery V
DD
, INT may be directly connected to
CLR, as in Figure 5. The only requirement is that the
microcontroller should be able to provide a high logic level
of 1.9V to SHDN. If the microcontroller V
CC
is greater than
W
U
U
the battery V
DD
, use Figure 6. The resistor dividers on CLR
and SHDN keep the voltages at these pins within the
LTC4150’s V
DD
range. Choose an R
L
value using Equation
11 and R1-R4 values using Equation 13. In either applica-
tion, the LTC4150 will capture the first assertion of INT and
wait at least 1
μ
s before resetting it. This insures that INT
pulses low for at least 1
μ
s but gives automatic INT reset.
